Use the midpoint formula to estimate the quantity of milk produced the second day. Assume that the
quantity of milk produced always follows a linear
pattern.
Day
Quantity (in ml)
First
360
Fifth
420
ml
Hint?
HINT: You actually need to use the midpoint formula
twice, since you need the midpoint of day 1 and day 5 to
get day 3, then the midpoint of day 1 and day 3 to get day
2!

375

Step-by-step explanation: 360+ 420/2 = 390

360 + 390/2 =375

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

hope this !
